I opted for the 17M2 and have never looked back!
It has the same report as a standard HV 22lr, doesen't tear up a squirrel for hunting, is accurate enough to hit a dime at 50 yards consistantly, will also shoot into a nickle at 100 yards, cheeper than shooting high quality target ammo for the .22, kills with much more zapp than it looks like it should, it's cute :roll: and just plain fun to shoot.
The reason I chose it over the 17HMR.
HMR is LOUD, it's too much for hunting meat game, not realy enough for coyote (my primary varmit shooting) more $$ to shoot.
Just my 2cents. :wink:
